Implementations

impl CachePairReader

pub fn get_directory_node<T: Into<PathBuf>>(&self, path: T) -> Option<Node>

Get the directory node for the given path.

pub fn get_file_node<T: Into<PathBuf>>(&self, path: T) -> Option<Node>

Get the file node for the given path.

pub fn directories(&self) -> &Vec<Node>

Get the directory nodes

pub fn files(&self) -> &Vec<Node>

Get the file nodes

pub fn get_data(&self, file_node: Node) -> Result<Vec<u8>>

Read the data without decompressing it for the given file node.

pub fn decompress_data(&self, file_node: Node) -> Result<Vec<u8>>
